25 Claims. (Cl. 12--37) This invention relates to machines for applying pressure to shoe bottoms and is herein illustrated as embodied in a sole attaching press of the wheel type having a number of pressure applying units located on the wheel.

In the manufacture of shoes in which the soles are attached by cement, after the sole has been placed on the shoe, it is necessary to apply a substantial amount of pressure against the bottom of the shoe so as to insure that the sole and shoe will be firmly bonded together. This pressure must usually be maintained for an appreciable time to obtain a strong adhesive bond. Because of the necessity of maintaining the pressure on the bottom of the shoe, it is the usual practice to perform thesole attaching operation on amachine having a number of pressure applying units which are moved successively into and out of the loading station at which the operator inserts and removes a shoe from the machine.

It is an object of the present invention to provide amachine for applying direct-pressure to the bottom of a shoe and maintaining this pressure for a period suflicient to allow the cement to bond properly. It is a further object of the invention to provide a machine of this type which is easy to operate and is mechanically of such simple construction that it may be manufactured at low cost and will not be subject to breakdown ue to mechanical failure.

Accordingly, the invention comprises a wheel or spider which is mounted for rotation on a horizontal axis. Each arm of the spider carries a pressure applying unit which is composed of a shoe support, a sole pad, and toggles, one at each end of the pad, operative to move the sole pad toward the support and thus apply pressure to the bottom of a shoe carried thereon. In order to straighten the toggles, there is provided a pair of pistons actuated by fluid pressure and operable through linkage to apply pressure at the knees of the toggles of the pressure applying unit which is at the loading station. In order to maintain the pressure on the shoe bottom from the time when the unit leaves the loading station until it returns thereto, there is provided a latch which looks the sole pad and support in pressure applying relation to one another during the rotation of the Wheel. Means are also provided for releasing this latch and effecting a movement of separation between the sole pad and the shoe support/as they move into the loading station. A further feature of the invention resides in the provision of a mounting for the shoe support whereby the latter may swing into and out of operative position about an' axis extending lengthwise of a shoe on the support and substantially parallel to the axis of the spider or Wheel. Means is also provided for automatical- 1y swinging the support into inoperative position line III-III of Fig. 2;

As illustrated in Figs. 1 and 2, the invention comprises a base 20 carrying a hollow horizontal shaft 22 on which is mounted a rotatable wheel 24. On this wheel or spider are mounted a number of pressure applying units each of which is composed of an arm 26 carrying a shoe support 28, a sole pad 30, and a pair of toggles 32. The machine is illustrated with twelve of these units, but it will be obvious that a greater or lesser number may equally well be employed. As illustrated, the shoe support 28 is of metal and of such shape and size that a shoe may be slipped over it, but, if desired, the support may be removed and a last carrier such as that illustrated in Fig. 8 comprising a heel pin 3| and a toe rest 33 may be substituted. For this purpose a shaft 34 (Fig. 4) is mounted in the arm and the shoe support is bored to fit over the end of this shaft and to be locked there by a clip 36 the ends of which fit over a rib 38 formed in a boring in the shaft. This clip is secured to a plate 4|] the periphery of which engages the support and holds it on the shaft. The support is secured against rotation relative to the shaft by a pin 42 which engages a slot 44 in the support.

The sole support or pad box comprises a metal base 46 the top surface of which is shaped to conform substantially to the bottom of a shoe.

The central portion of the upper surface of this base is hollowed out to receive a rubber pad 48 which is preferably molded to conform to the shoe bottom and thus insure equal pressure against the sole at all points. Adjustment of the pad box in a heightwise direction relative to a table 50 upon which it rests is effected by .two adjusting screws 52 bearing against pins 54. The ends of these pins 54 are beveled and engage correspondingly beveled surfaces on the ends of two pins 56 secured to the table 50 by set screws 58. Thus, turning the screws 52 will raise or lower the pad box relative to the table 50 upon which it rests.

Movement of the pad box 30 toward and away from the shoe support, that is, into and out of pressure applying position, is effected by the toggles 32. The upper ends 60 of the toggles are connected to projections 52 extending downwardly from the table, and the lower links 04 of the toggles are connected directly to the spider 24. Thus, by pressure upon the knees of the toggles, the pad box is moved upwardly toward the shoe support and into pressure applying position. In order to straighten the left-hand or forward toggle, a lever 66 is pivoted at 68 in the shaft 22. The upper end of this lever carries a roll 10 which bears against the knee of the toggle and the lower end of the lever carries another roll 12 which bears against a similar roll I4 carried by a piston I6 mounted for sliding movement in a cylinder TI in the hollow shaft 22. The other toggle has bearing against its knee a roll I8 carried by a cylindrical plunger 80 mounted in the arm 26 and held against rotation relative thereto by a pin and slot arrangement 82. A roll 84 carried by one end of a lever 86 pivoted at 88 in the frame 20 engages the end of this plunger 80 to cause it to straighten the toggle knee at the appropriate time. The other end of the lever 06 is' connected by a link 90 to a piston 92 similar to the piston I6 and slidable in the cylinder I1. Thus, movement of the two pistons I6 and 02 applies pressure to the knees of the toggles 32 and causes them to straighten.

The pistons 16 and 92 are operated by means of compressed air which is introduced into the cylinder between the two pistons through a tube 94, gasket members 95 being provided to assist in sealing this cylinder. The air tube 94 is connected to some suitable source of compressed air I by a valve 96 which is operated by a rod I02 connected to a slotted arm I04 (Fig. 3) carried by an air treadle rock shaft I06. The valve is provided with an exhaust port I08 arranged so that when it is held in closed position by a spring II-I the air in the space between the pistons 16 and 92 is permitted to escape to allow the pistons to be drawn inwardly toward each other by a spring IIZ. When the air treadle valve 98 is moved downwardly, however, the exhaust port I08 is first closed and then air from the source of'supply I00 passes through the valve 98 into the tube 94 and thence into the chamber between the pistons 15 and 92.

As the air causes the pistons to move apart and thus straighten the toggles, two arms H4 (Figs. Zand 4). each rigid with the lower links 64 of the toggles swing downwardly toward one another. Continued movement of the toggles lifts the table 50 upwardly until a latch member H6 pivotally carried on the spider 24 and having wings III to prevent it from falling between the the position shown in Fig. 4. In this position shoulders I22 of, the latch engage the ends of the arms H4 and thus hold the toggles in their straightened position from the time that the unit moves out of the loading station at the top of the machine until the wheel has made one complete rotation and is carrying the unit back into the loading station again.

The release of the latch H6 and the breaking of the toggles may advantageously take place as the unit moves into the loading station. Referring now to Figs. 9 and 10, a stationary cam H8 which is carried by the hollow shaft 22 is arranged in such position as to engage a tail piece I24 of the latch I I 6 and cause the latter to move out of engagement with the arms H4 as the unit is moving into the loading station. To insure that the toggles will be broken, there are also provided two stationary cams I26 which engage beveled portions 128 at the ends of the arms H4 and as the unit is moved into loading station, the cams lift these arms upwardly and cause the toggles to be broken. It is to be noted that the configurations of the cams H8 and I26 are such that the latch H6 is first released, the arms H4 are given an initial impulse by the bump I30 of the cam I26 and then are moved progressively upward. The cam H8 is so constructed that when the pressure applying unit is at the loading station and the support and pad box are separated, the camand the latch are not in engagement, but the wings of the latch are held lightly against the back sides of the arms H4 by the spring I20. As the toggles straighten, the arms H4 slide over the surface formed by the wings and the ribs I32 on the latch. The latch is thus kept out of the way of the arms until they have reached a point in their downward movement such that the shoulders I22 may slip over the ends of the arms and hold the pad box and support in pressure applying position. It is to be noted that the movement of the latch imparted to it by the spring I20 is limited by a lug I3I on the latch which strikes the under side of the table 50 when the latch is in position to engage the ends of the arms H4.

In order to simplify removal of a shoe from the support and putting another one on, it has been found desirable to swing the shoe support about an axis lengthwise of a shoe and substantially parallel to the axis about which the wheel rotates. To this end the shaft 34 upon Which the support is mounted is journaled for rotating movement in the end of the arm 26 so that the support may be swung from the operative position shown in Fig. 8 into the inoperative position illustrated in Figs. 1 and 2. It is desirable that this swinging movement should be effected automatically as the unit moves into the loading station. To accomplish this, the shaft 34 is bored to receive a coil spring I36 through the center of which passes a rod I30, the spring being under clockwise stress, as viewed in Fig. 5, when the support is in operative position. A head I40 on this rod is of the same diameter as the bore in the shaft and is secured therein by a pin I42. One end I 44 of the spring is secured to the head of this shaft and the other end is fastened to a plug I46 fitting loosely in the end of the hollow shaft 34. As shown in Fig. 5, the end I43 of this plug is slabbed off to fit into a slot I50 cut in the end of a clip I52 secured to the arm 25. Thus, the support 28 is urged in a clockwise direction as viewed in Fig. 5 by the spring I36.

In order, however, to hold the support in operative position once it has been swung to that point,

there is provided a latching disc I54 (Figs. 4, 6, and 7) which is made rotatable with the shaft by a pin I56 affixed to the shaft 34 and entering a slot I51 in the latching disc I54. The disc is slotted at I58 (Fig. 6) to receive the end of a pin I60 (Fig. 4) slidably carried in a boring in the arm 26, the end of the pin being yieldably held in the slot by a spring I62 acting between an ear I64 integral with the pin I60 and one arm I66 of a bell crank lever I68. When the support is swung downwardly into operative position against the tension of the spring I36, thus rotating the disc I44, the pin I60 slips into the slot I58 in the latching disc and thus holds the support against reverse swinging movement which would otherwise be imparted to it by the tensioned spring I36. A recess I in the latching disc at the top side thereof limits the swinging movement of the support in its rotation from operative to inoperative position.

It is desirable that the swinging movement of the form to inoperative position should be effected automatically as the unit moves into the loading station. To this end a rod I12 is pivotally connected to an ear I" carried by the table 58. A latching member I16 is secured to the end of the rod I12 and a lug I78 carried by the latching member engages a pin I80 on a horizontal arm I8I of the bell crank lever I68. The arm 66 of the bell crank engages a lug I82 on the pin I68. Thus, downward movement of the table 58 causes the bell crank lever to turn in a counterclockwise direction as viewed in Fig.4, causing the pin I60 to move out of the slot I58 to permit the latching disc to rotate. The support is now free to swing 180 in response to the tension of the spring I86, this swinging movement being stopped by the shoulder I10 on the latching disc I54. Rotation of the disc causes a cam surface I84 (Fig. 6) on the latching disc to move the pin further in the direction in which it has been carried by the arm of the bell crank; As the pin I88 moves in this direction it strikes a lug I86 (Fig. 4) on the latch member I18 and forces the latter to the left sufficiently so that the pin I86 no longer engages the lug I18, leaving the bell crank 468 free to be returned to its normal position by a spring I88. The parts are then in the relation shown in Fig. 11. When the support is swung down into operative position, the spring I62 causes the pin I60 to move into the slot I58, thus locking the support in operative position. When the toggles are straightened and the rod I12 moves upwardly, the beveled upper surface I88 of the lug I18 strikes the pin I88 and causes the latching member to move to the left against a spring I92 until the latching member has risen sufficiently to permit the spring I92. to pull it rearwardly, thereby bringing the lower surface of the lug 516 into engagement with the pin I80 in position to operate the latching pin I 60 when the pad box 38 and the plate 50 move downwardly.

It is to be noted that when the support is swung into operative position and is locked there by the pin I60 it will always be in a definite relation to the pad box 38. Consequently, if a sole is properly located on the pad box, it must be attached to the shoe in proper position. To assist in positioning the sole on the pad there is provided a toe gage I94 (Figs. 1, 2, and 4) which is fastened to the metal base 46 of the pad box and has a V- shaped notch I86 into which the toe end of the sole may be inserted. The heel end of the sole is positioned by a pin I88 which enters a hole punched at the proper location in the heel end of the sole. Further to insure that the shoe and the sole will be in proper registration with one another the support 28 is made expansible, so that the shoe will fit tightly thereon. The heel end of the support is recessed to receivean approximately triangular block 200 which is slidable in a direction lengthwise of the shoe upon the inclined surface 202 which forms one side of the recess. Sliding movement of thetriangular member is effected by means of a toggle composed of a link 284 pivoted at206 in the triangular member and a second link 208 which is pivoted at 2I0 in the support and is integral with a handle 2I2 by which the toggle may be straightened or broken. By this means it will be made certain that the shoe is always in proper position on the support, and thus if the sole gages have been set properly the shoe and sole must come together in exactly the proper registration.

Power for moving successive units into and out of the loading station is provided by a motor 2 I4 connected by a worm and worm gear 2I6 to a pulley 218. A belt 220 passes over this pulley and a second pulley 22 2 mounted for free rotation on a shaft 224, the second'pulley 222 being rigid with a fly wheel 226 also freely rotatable on the shaft 224. A clutch 220, which may advantageously be of the cone type, is provided to connect the fly wheel to the shaft 224'. A gear 232 is also secured to the shaft 224 and this gear, through intermediate gears 234, drives a gear 236 integral with the wheel. The gear ratios are such that a single revolution of the clutch and the shaft 224 causes the spider to rotate A of a revolution, thus moving one pressure applying unit out of the loading station and moving the next succeeding unit into that position.

A treadle 238 is provided to operate the clutch 228. This treadle is connected by means of a rod 240 to a latch member 242' having a lug 244 which engages a pin 246-carried by one arm of a bell crank 248 pivoted on the frame 20. The other arm of the bell crank carries a shifter fork 250 which engages a groove in the clutch. Downward movement of the rod 240 causes the lug 244 to swing the bell crank about its pivot, thus moving the clutch 228 into engagement with the fly wheel. As the shaft 224 approaches the end of one revolution, a rotating cam 252 integral with'the shaft strikes the latching member 242 and moves it forwardly .so that the lug 244 no longer engages the pin 246. A spring 254 then causes the bell crank to swing in a clockwise direction, as shown in Fig. 2, thus disengaging the clutch and stopping the movement of the wheel.

A lever 256 pivoted on the frame engages one of a series of notches 258 in the wheel in order to lock the latter in position so that the rolls I0 and 84 will engagethe knees of the toggles at the proper points. When the treadle rod 240 is depressed, a collar 260 strikes the end of the lever 256 and swings it out of locking position, thus permitting the turret to rotate.

The function of the various parts of the machine having been explained in connection with the description of the details of the machine, only a brief summary of its operation is necessary. With the parts in the position shown in Figs. 1 and 2, the operator slips a shoe over the form 28 or if a last support is being used places a last and shoe on the support and sets a sole 0n the pad in proper position according to the sole locating means. The support is next swung downwardly into operative position over the sole where it is locked by the pin and thelatching disc. He then d'epresses the air treadle IE6 and causes air under pressure to be introduced into the space between the two pistons 16 and 92. As the toggles are straightened to the position shown in Fig. 4, the engagement of the shoulders I22 of the latch and the arms IE4 locks the toggles in pressure applying position, with the sole pressed against the shoe bottom in the relation previously determined by the setting of the sole gages. The operator then releases the air treadl'e ms, closing the inlet valve, opening the exhaust port I08, and permitting the spring H2 to pull the pistons and 92 into their normal position. The operator then depresses the clutch treadle 238 thereby causing the wheel to be rotated A of a revolution and moving the next succeeding pressure applying unit into the loading station at the top of the machine.
